Based on the calculations, the number of books that were bought by Hugh are 4 books.

<h3>How to calculate the number of books?</h3>

In order to determine the number of books that were bought by Hugh, we would substitute the value of the number of magazines into the given equation and then evaluate as follows:

3.95m + 8.95b = 47.65

3.95(3) + 8.95b = 47.65

11.85 + 8.95b = 47.65

8.95b = 47.65 - 11.85

8.95b = 35.8

b = 35.8/8.95

b = 4.

In conclusion, the number of books that were bought by Hugh are 4 books.

Complete Question:

Hugh bought some magazines that cost $3.95 each and some books that cost $8.95 each. He spent a total of $47.65. If Hugh bought 3 magazines, how many books did he buy? The equation that models the problem is 3.95m + 8.95b = 47.65, where m is the number of magazines and b is the number of books.

The diagram shows a trapezium PQRS. Find the length of side PQ, in cm​
mixas84 [53]

Answer:

30 cm.

Step-by-step explanation:

Draw a line from R perpendicular to PQ to meet PQ at T.

RQT forms a right-angled triangle  with RT = SP = 15.

So tan 36.87 = RT / TQ

tan 36.87 =  15 / TQ

TQ = 15 / tan 36.87

=  20 cm.

Now  PT = SR = 10, so

PQ = 10 + 20

= 30 cm.

Suppose I have an urn with 9 balls: 4 green, 3 yellow and 2 white ones. I draw a ball from the urn repeatedly with replacement.
Mrrafil [7]

Answer:

E(X_n)=\frac{2(n-1)}{27}

E(y)=\frac{14}{9}

Step-by-step explanation:

From the question we are told that:

Sample size n=9

Number of Green g=4

Number of yellow y=4

Number of white w=4

Probability of Green Followed by yellow P(GY) ball

 P(GY)=\frac{4}{9}*\frac{3}{9}

 P(GY)=\frac{4}{27}

Generally the equations for when n is even is mathematically given by

 Probability of success P(S)=\frac{4}{27}

 Probability of Failure P(F)=\frac{27-4}{27}

 Probability of Failure P(F)=\frac{23}{27}

Therefore

 E(X_n)=\frac{n}{2}*P

 E(X_n)=\frac{n}{2}*\frac{4}{27}

 E(X_n)=\frac{2n}{27}

Generally the equations for when n is odd is mathematically given by

 \frac{n-1}{2}

 E(X_n)=\frac{n-1}{2}*\frac{4}{27}

 E(X_n)=\frac{2(n-1)}{27}

b)

Probability of drawing white ball

 P(w)=\frac{2}{9}

Therefore

 E(w)=\frac{1}{p}

 E(w)=\frac{1}{\frac{2}{9}}

 E(w)=\frac{9}{2}

Therefore

 E(y)=[E(w)-1]\frac{4}{9}

 E(y)=[\frac{9}{2}-1]\frac{4}{9}

 E(y)=\frac{14}{9}
